TXD Sliding Vane Pumps

Part of the Iron Line, Blackmer® TX/TXD/TXDI Series Sliding Vane Pumps are durable pumps utilized for fast and quiet operation. The sliding vane design provides sustained performance and trouble-free operation. These pumps are equipped with FKM O-rings and Blackmer mechanical seals that are compatible with all biodiesel and ethanol blends. TX/TXD/TXDI options include corrosion resistant relief valve, pneumatic relief valves and Buna or PTFE elastomers and seals.

Features and Benefits

Double-ended drive shaft for either clockwise (RH) or counterclockwise (LH) rotation
External roller ball bearings support the rotor from both sides, creating a stable environment for the internal mechanical seals
Dual-ended shaft on 2-, 2.5- and 3-in models simplifies installation
Blackmer mechanical seal and ball-bearing construction provide maximum reliability
Internal mechanical seals allow for extended dry run and continuous operation with non-lubricating liquids
Symmetrical bearing support assures even loading and wear for long life
Adjustable relief valve protects pump against excessive pressures
T-type strainers are available to protect pumping systems from damage caused by welding slag and foreign matter in pumps and tanks
High volumetric efficiency and symmetrical bearing support means less required horsepower than other PD pumps, meaning a cost savings on both motor operation and electricity
External ball-bearings are isolated from pumpage by mechanical seals to maximize bearing life and minimize contamination risk
Easy maintenance: vanes can be easily replaced -- without removing pump from truck
Advantages of sliding vane technology:
- Unique sliding-vane pump design self-adjusts for wear to maintain flow rates
- Excellent self-priming and dry-run capabilities
- Sliding vane design provides sustained performance and trouble-free operation
- High suction lift and line-stripping capabilities
- Low maintenance and low life-cycle costs
